i had my first anxiety on 2017 when i was in the last year in my high school and it lasted a year. the first symptoms i had was less sleep and when i sleep then wake up i would feel like i never had a sleep, another symptom was i had a racing heart beat that when i hear my pulse i would ask my self a lot of questions which would make me panic and make my pulse more faster. for that year i had the anxiety, i had reached a very high level in the anxiety like i used to talk to myself and ask what is happening to me, i used to google my symptoms and google would respond like i had a non-functioning glands and felt hopeless and would be like this forever. i used to cry a lot, but i had this part that made me feel better which was PRAYING. i started praying my 5 prayers everyday and reading Quran. After 2days i would sleep better, my pulse went back to normal and the most thing i missed a lot happiness. Afterwards i learnt how to control my anxiety and stress and whenever i feel some pressure i would do a pro-longed sujood and pray. the reason why posted this was i really feel you guys and when i read your posts, i saw myself in 2017 when i was hopeless so i wanted to tell you guys not to worry and you gonna have your life back and will be happy Insha Allah. just be connected to Allah
David D. Burns recommends breathing exercises for those suffering from anxiety. One such breathing exercise is a 5-2-5 count. Using the stomach (or diaphragm)—and not the chest—inhale (feel the stomach come out, as opposed to the chest expanding) for 5 seconds. As the maximal point at inhalation is reached, hold the breath for 2 seconds. Then slowly exhale, over 5 seconds. Repeat this cycle twice and then breathe 'normally' for 5 cycles (1 cycle = 1 inhale + 1 exhale). The point is to focus on the breathing and relax the heart rate. Regular diaphragmatic breathing may be achieved by extending the outbreath by counting or humming.
Cognitive Behavioral Therapy (CBT) is an example of one type of psychotherapy that can help people with anxiety disorders. It teaches people different ways of thinking, behaving, and reacting to anxiety-producing and fearful objects and situations. CBT can also help people learn and practice social skills, which is vital for treating social anxiety disorder.
Anxiety attacks usually peak within 10 minutes, and they rarely last more than 30 minutes. But during that short time, the terror can be so severe that you feel as if you’re about to die or totally lose control. The physical symptoms of anxiety attacks are themselves so frightening that many people believe they’re having a heart attack. After an anxiety attack is over, you may be worried about having another one, particularly in a public place where help isn’t available or you can’t easily escape.
Social Anxiety Disorder;Fear of social situations in which the person is exposed to unfamiliar people or to possible scrutiny by others. The individual fears that he or she will act in a way (or show anxiety symptoms) that will be embarrassing and humiliating, often times leading to avoidance of social situations and severe distress when participation in social situations can't be avoided. 
Before SSRIs and SSNRIs became available, medications from the group known as the tricyclic antidepressants (TCAs) were often used to address panic disorder. Although TCAs have been found to be equally effective in treating panic attacks, SSRIs and SSNRIs have been proven to be safer and better tolerated. Therefore TCAs are used much less often than they were previously.
People with generalized anxiety disorder (GAD) display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.
